摘要： PURPOSE:To obtain a carrier capable of remarkably improving lytic efficiency of bacteria without damaging useful microorganisms and causing pollution, by immobilizing bacteriophages capable of infecting bacteria, lysing the bacterial cells for propagation in a molded product of chitosan in a high concentration. CONSTITUTION:The titled molded product obtained by converting chitosan which is naturally occurring polysaccharides into an acidic solution, forming the solution into the shape of grain, fiber, film, etc., in a coagulation bath consisting of a basic solution and dipping the formed chitosan in a solution containing bacteriophages for 1-4hr while shaking. The resultant molded product is used for the purpose of preventing marine microorganisms from attaching to equipment contacting or utilizing seawater and sterilizing efficiency is higher than that in a method for mixing a bacteriophage solution with seawater and circulating the mixed seawater through the equipment without adversely affecting the surrounding ecosystems.

摘要： PROBLEM TO BE SOLVED: To he a regenerated cellulose fiber having warmth retaining effect due to hygroscopic heat build-up by improving the hygroscopic property of cellulose fiber. SOLUTION: The modified regenerated cellulose fiber having a hygroscopic heat build-up property is obtained by making a regenerated cellulose fiber contain an acidic polymer having carboxyl group, crosslinking the fiber and then by performing alkali treatment. The content of the above acidic polymer is 3-25 wt.% based on the total weight of the modified regenerated cellulose fiber. The acidic polymer is soluble in sodium hydroxide and coagulates in a coagulating and regenerating bath for a cellulosic viscose solution. The resultant modified regenerated cellulose fiber has a hygroscopic heat build-up temperature of 7.5-11.5 deg.C.

摘要： PURPOSE: To obtain the subject woven fabric having excellent W&W properties and tear strength and good in shape stability excellent in safety by treating a cellulosic fiber woven fabric with a mixture dispersion containing specific three components in the same bath. CONSTITUTION: This method for processing a cellulosic woven fabric is to treat the woven fabric of a cellulosic fiber material of natural cotton or regenerated fiber such as rayon in a dispersion solution prepared by mixing a silicone- based softening and finishing oil and/or a urethane-based resin with bis(β- hydroxyethyl) sulfone in the same bath and carry out the cross-linking treatment. Thereby, the resultant fabric has unconventionally high W&W properties and is capable of manifesting a sufficient tear strength withstanding practical use. Since the cross-linking is carried out with a nonformaldehyde-based cross-linking agent according to this method, the toxicity is not exerted on the human body.
